Here, Live Science keeps you abreast of all the fascinating physics discoveries.Physics
New images reveal that one of the strangest asteroids in the solar system is also the most covered in craters, after billions of years plowing through the asteroid belt like a runaway train.
Life on Earth likely began with the bubble-like membranes that surround our cells. Similar membranes probably wouldn't form on Titan, according to quantum mechanics.
For the first time, astrophysicists have detected a pattern in fast radio bursts, one of the most mysterious phenomena in the universe.
The way the fabric of space and time swirls in a cosmic whirlpool around a dead star has confirmed yet another prediction from Einstein's theory of general relativity, a new study finds.
When two neutron stars slammed together far off in space, they created a powerful shaking in the universe — and their echoes could violate Einstein's theory of relativity.
Scientists are searching for a ghostly neutrino particle that acts as its own antiparticle. If they find it, the discovery could resolve a cosmic conundrum: Why does matter exist at all?
String theory is a powerful idea, unfinished and untested, but one that has persisted for decades despite inauspicious beginnings.
Researchers claim to have found serious fault with the existence of dark energy, but not everyone is buying into it.
